Windows 10 (No Audio and Wifi on iMac)

Question

Wednesday, June 29, 2016 8:44 PM

Hi,

I have a iMac 5K (late 2015, 462XX).

I work with Windows 10 and installed it with Bootcamp on the internal SSD,

it worked perfectly, but since a few days (few new updates installed) there is no Audio und Wifi on Windows available.

It works perfectly on MacOS, but not on Windows. Both tray icons have red crosses.

I hope anyone could help.

I uninstalled bootcamp drivers, i also deactivated and activated my wireless network adapter,

but it also doesn't work. Same with Audio.

Its really frustrating.

Regards 

Ronny

Hello there, 

You need to download and install the latest update for Boot Camp, follow these steps: 

1. Go to : http://www.apple.com/support/bootcamp/

2. Click Downloads

3. Scroll until you find the latest Boot Camp update for the Mac system you're running 

4. Click Download

5. Follow the on screen instructions to download and install the latest software update for Boot Camp

6 Restart your Mac

This should hopefully solve the issue.

Hello,

thanks for your answer.
But the problem can't be fixed in this way. I repaired my bootcamp drivers, I uninstalled the drivers
and I also uninstalled the driver itself in the device-manager. I performed all steps from the website above.
Sound and Wifi works correctly until a few new updates and features was installed on Windows 10 (few days ago). 
It is really important to me to fix this issue.

Hi, 

it doesn't solve my problem.
I uninstalled the drivers in device manager and restarted the iMac.
It installed the drivers again but doesn't work.
There are red crosses in wifi and audio.
I installed Windows 10 (1511 November Update ISO) with Bootcamp.
It workes perfectly. But after a few days it installed new updates over windows update.
It shows a message (new features installed) and restarted, after that there are no wifi and
audio available.

I really need help to fix this.
Regards

Hi Ronny,

Would you please let me know the update history? Post back the list you mentioned which may cause this issue.

Please uninstall them or get system restored back to see if this issue can be fixed. Restart each time after uninstalling each update and let me know which one is the root cause.

In addition, please pay attention to check if there is any driver update included in them.

Hello,

I still have the same problem since july 2016.
I uninstalled my boot camp partition so many times. 
I don't have WLAN and Audio. All other things are okay.

Current configuration: Windows 10 - 1607 Anniversary, iMac 17,2 Late 2015 27" Retina with 256GB SSD.
I have also tried original Windows 10, also 1511 and now 1607.
On my main SSD, I have MacOS Sierra.
I have a external SSD connected via Thunderbolt. 

Installation-Steps:

  1. Open Bootcamp, create partition and load Windows 10 1607 iso
  2. Windows 10 Setup - I set the installation drive to the external SSD,
  3. After Installation, all works fine for a few starts. Windows 10 works perfect from external sad with sound and wifi.

4. After a few starts, audio and wifi are not available anymore, red cross on both icons in sys-tray.
5. Short time bevor I setup my Wifi, I disabled all windows updates, and set the wifi to a metered connection, also group policy, because I thought it would be a windows update. But it wasn't. Because no updates are installed and I have no wifi and audio.

I hope anyone could help.
I am really frustrated since july, because I need to work on mac and also on windows.
I have no idea what I can do!?

I ended up buying a USB Audio Interface in order to get audio.   I bought a Creative Sound Blaster Play-2, which had my Windows audio up and running right away with no other drivers.

Than I need two extra devices, wifi and audio-usb device. I hope this is a joke. It isn't funny :'(

I had this same problem (wlan and audio devices not working) on my iMac 5k running Windows 10 build 1511. As soon as Windows would update, the wifi would say "no wireless networks found" and the audio would have the red icon over it.

Reinstalled many times and for a long time the only workaround was to disable the Windows Update service, preventing any updates. This is not a great solution. Until I finally figured out what the updates were doing. It isn't the updates per se, nor is it the bootcamp drivers. It is that one of the updates enables Hyper-V virtualization, and for some reason this interferes with the wlan and audio components.

Disabling Hyper-V finally resolved it for me.

Go to Control Panel/Turn Windows Features On and Off and uncheck the Hyper-V checkbox.

Hoping this can help someone else, what a frustrating experience.

This worked for me to re-enable audio, thanks!

Hi,

I have tried it a few times to disable hyper-v.
After disabling hyper-v in Windows Features, it can't finish the feature installation after restart and will enabling it again.

Sometimes I will throw out the iMac out of the window.
But I know, It's not caused by Apple. It's caused by Microsoft's HyperV.

Hope anyone could help.
